മലയാളത്തില്‍ എങ്ങിനെ മെയില്‍ അയക്കാം..?

1.First of all you have to make an id in g-mail
go to www.gmail.com
then register an i d there.
then, read this

.
ഇടതു വശത്തായി കാണുന്ന Compose Mail എന്നാ ബട്ടണ്‍ ക്ലിക്ക് ചെയ്‌താല്‍ നമ്മള്‍ മെയില്‍ കമ്പോസില്‍ എത്തും.
എന്നിട്ട് വലതു വശത്ത് മുകളില്‍ കാണുന്ന സെറ്റിംഗ്സ് ക്ലിക്ക് ചെയ്യുക.
അതില്‍ enable transliteration എന്നൊരു കളം ഉണ്ട്.
അതില്‍ ക്ലിക്ക് ചെയ്തു
അവിടെ മലയാളം സെലക്ട്‌ ചെയ്യുക
എന്നിട്ട് താഴെ വന്നു സേവ് ചെയ്താല്‍ മതി
വീണ്ടും തിരിച്ചു കമ്പോസ് മെയിലില്‍ വന്നിട്ട്
അതിന്റെ പാനലില്‍ അ എന്നാ അക്ഷരം undallo
അതില്‍ ക്ലിക്ക് ചെയ്താല്‍;
ആ അക്ഷരം നീല നിരത്തില്‍ ആവും
ഇനി താഴെ മന്ഗ്ലിഷില്‍ ടൈപ്പ് ചെയ്താല്‍
അത് മലയാളം ആയി മാറും.
അങ്ങിനെ ടൈപ്പ് ചെയ്യുമ്പോള്‍ ചില വാക്കുകള്‍ നമ്മള്‍ ഉദ്ദേശിച്ച മാതിരി വരില്ല
അപ്പോള്‍ ആ വാക്കിന്റെ ഇടക്കൊന്നു വെറുതെ ക്ലിക്ക് ചെയ്താല്‍
അതിന്റെ തെഴെക്ക് വേറെ വാക്കുകള്‍ വരും
അതില്‍ നിന്നും ആവശ്യമുള്ളവ തെരഞ്ഞെടുക്കാം.

How to send a voice mail to your friend using Windows XP?

E-mail is a most popular and effective way to communicate with others through the internet. You can send documents, pictures and other types of files to any destination but the interesting thing is that you can send also your voice in a mail by attaching the file with e-mail. In windows XP, you can record your voice using Sound Recorder and a microphone options.

Follow the given steps to record your voice in windows XP:

To use this feature, you will need to be logged into your computer with administrative rights.
To start recording process, first make sure you have attached a microphone to your computer.
First click on Start button> All programs> Accessories> click Entertainment and then click on Sound Recorder option.

Now a small "Sound - Sound Recorder" will appear, go to File menu and click on New to start a new file for recording.

Click on Record button to start recording process and start talking then click on Stop button to stop the recording.

Now again click on File menu to save this file with .wav extension to a folder of your choice.


Now send this voice file as an attachment via e-mail message to your friends.

How to Retrieve Data Off a Crashed Hard Drive

The hard drive has the shortest life expectancy of all components, but when it inevitably fails it’s always when you least expect it. It’s an inevitability, and it always happens when you’re least prepared - the hard drive crash. Sure, you might notice it’s taking a bit longer to boot, or there’s an occasional click that just doesn’t sound right, but it’s still a surprise the day your computer fails to boot. How do you get your data off that hard drive once it’s no longer able to boot? Is it still possible? This depends on what exactly went wrong with your drive. It is safe to assume, however, that will the proper method, you will be able to retrieve at least part of your lost data.


Below are five different methods for getting documents, pictures, and other important files off a crashed hard drive.

1. Use an External Case

This method is the most simple available, and for many people it is also the solution they need. Simply purchase an external hard drive case that allows you to plug your hard drive into a computer with a standard USB cable. Remove the crashed hard drive from your computer and carefully insert it into the external case (make sure you ground yourself before touching it), then plug it into a different system and try to open the drive. There’s a good chance you’ll be able to navigate into your documents and other folders and copy them onto a different hard drive.

2. Use a LiveCD

Don’t have access to a second computer for doing as you please? This method will be ideal, then. You’ll need to get temporary access to a computer with Internet and a DVD burner. Download a Linux LiveCD - d**n Small Linux is the smallest, but also has issues mounting hard drives. The most simple for an average computer user would be Puppy Linux. It has a larger file size, but should recognize your drive.

Burn the Live CD ISO to a CD and insert it into your computer (the one with the crashed hard drive). Restart the computer and when it the computer logo appears, press F2 (or whatever key for your system) to enter BIOS. Change the boot sequence to CD first, Save and then Exit.

The Live CD will start, simply follow the directions on the screen–don’t worry, nothing is being done to your hard drive. The OS will start, and you should see your hard drive mounted on the desktop–something like “60GB”, etc. Plug in a second drive and copy and paste the folders over.

3. Data Recovery Software

Do the above solutions have your head spinning? If you want something a little less complicated, you may want to give recovery software a go. There are a number of different free recovery tools available, and you may be one of the lucky users who have success with the programs.

There are a large number of programs available, but the quality of each varies. A good place to start would be Data Disc Recovery–it’s free, easy to use, and works on crashed drives (it can also retrieve deleted files and others). If one doesn’t work, try a different one.

4. Freeze It

This method surprises many, but it actually does work (depending on what happened to the drive). The idea is that freezing it will constrict loose parts long enough for the drive to work properly. Make sure you have a computer ready to plug the drive into and an external case. Place the hard drive into a freezer bag, seal it tightly, and put it in the freezer overnight. The next day, remove it from the bag and put it in the external drive case. Transfer the data from the drive before it warms too much and crashes again.

5. Get a Pro

If all else fails, you either have to accept that the data is gone or, if the data is really important, take the hard drive to a professional. It will be expensive, but there’s a good chance a pro will be able to retrieve some of the data for you.

Make FireFox run Faster

Here’s something for broadband people that will really speed Firefox up:

1.Type “about:config” into the address bar and hit return.

Scroll down and look for the following entries: network.http. pipelining network.http. proxy.pipelining network.http. pipelining. maxrequests

Normally the browser will make one request to a web page at a time. When you enable pipelining it will make several at once, which really speeds up page loading.

2. Alter the entries as follows:

Set “network.http. pipelining” to “true”

Set “network.http. proxy.pipelining” to “true”

Set “network.http. pipelining. maxrequests” to some number like 30. This means it will make 30 requests at once.

3. Lastly right-click anywhere and select New-> Integer. Name it “nglayout.initialpai nt.delay” and set its value to “0″. This value is the amount of time the browser waits before it acts on information it receives.

If you’re using a broadband connection you’ll load pages MUCH faster now!

Vista, Internet Explorer tips


Internet Explorer

Is tabbed browsing cluttering up your life?
In the Tools menu, select Internet Options. In the General tab, under Tabs, click the Settings button. Uncheck the topmost checkbox, which is labelled Enable Tabbed Browsing (requires restarting Internet Explorer), and click OK. To enable the tabbed browsing function later, just go back and select this option, and save your preferences.

Find on the Web Page
If you want to search for a particular word or phrase on the web page you’re viewing and can’t be bothered to read through every paragraph just press Ctrl and F together and type the word or phrase you want.

Display the Address bar history
A handy short cut to display the address bar history on the Internet Explorer is to press F4.

Open the Organize Favourites Dialog Box
To open the Organize Favourites Dialog box, press Ctrl and B together.

Windows Vista

Search for a file in Windows Vista
One of the ways to search for a file on Windows is the Search box available in every folder. You can type in any word associated with the file you’re looking for; Windows will look for that word in the file names, file contents, and file properties of all the files in the current view. To filter your search, say by files modified on a particular date, you can type ‘modified: ’ in the Search box. Similarly, to search only by file name, type ‘name: ’.


Now launch programs by searching for them
Starting up an application was never easier or quicker. No need to go through the Start menu and then several sub-menus. Just start typing the name of the program into the bar at the bottom and have Vista bring up the name of the program you need instantly!

A quicker way to launch your programs
Windows Vista assigns shortcuts to all the items in your Quick Launch toolbar, on its own, depending on the icons’ positions in the sequence. So if you want to open the program whose icon is the fourth in your Quick Launch bar, just press the Windows key + 4.

Clear up your Windows Sidebar
Is your Sidebar cluttering up your life? To get in a little breathing room, right-click gadgets that you don’t use frequently and change their opacity settings to 40 percent. These gadgets will now fade out of view when you are not using them.

Set a new theme for your PC
To change your Windows Vista theme, right-click your desktop and select Personalise. Next, click Themes; in the dropdown menu, choose the theme you want, and click Apply.

Clean up your temporary files
If you’ve recently been doing something with your computer that generates a lot of temporary files, you may want to make sure all those files are cleaned out of your system to free up precious space. To do this, just enter %TEMP% into your Start menu search box and press Enter. The temporary files folder will open, allowing you to delete files and prevent unnecessary clutter.

Speed up your system
Is your PC running slowly? Go to your Power Options control panel and look for the Power Saver setting that is set at 50 percent (default setting in Vista). Change this setting to High Performance and let your PC run faster.

Check for memory issues with your PC
Worried about memory defects in your PC? You can use Vista’s in-built tool to diagnose issues. Enter the word “memory” into your Start menu search box, and you will be taken to the Memory Diagnostics Tool. A dialog box will open and ask you whether you want to reboot your PC immediately or later. Vista will then run the Memory Diagnostic Tool while starting up.


Resize icons on the fly
If you want to resize the icons quickly in Windows Vista Explorer, press and hold the Ctrl key, and scroll up or down with the mouse wheel.

Faster shortcuts in Vista
Go to the Control Panel and search for the term “underline”. In your search results, you’ll get a link for Underline keyboard shortcuts and access keys. Click this, and in the next screen, go to the checkbox for Make it easier to use keyboard shortcuts. Select this. Now, whenever you go to any menu, the access keys for each function will be underlined. Pressing Alt with this key would enable the function.

How to improve your dialup modem preformance?

You can't assume that just because you connected at a speed like 48.3KBps that you will stay there. Today's modems automatically fall back to a lower speed if the line noise is too high to maintain a faster connection, but sometimes they fall back too soon or too far.

Here's how to do it:


Click Start the button.
Select Settings.
Click Control Panel.
Double-click on the Modems icon.
Select your modem.
Click the Properties button.
Click the Connections tab.
Click the Advanced button.
In the "Extra settings" field, type S36=7
Click OK to save your settings.

How The Internet Works

Neon_Internet_Cafe_Open_24_HoursOnce you finish this article, I’m sure you’ll be amazed that the Internet works at all! It’s easy to complain about slow download speeds, or lost e-mail, but, geez, it’s the Internet!

Ten years ago most of you were still buying magazines, and renting videos, and going to the post office, and ordering things from the Sears catalogue. The only thing cooler would be the ability to teleport ourselves through it.

Look at a map of the Internet sometime and you’ll see that it is like a million superhighways with no lines painted on the road. It’s a snake pit of computers attaching to modems attaching to phone lines, or cable, or satellites, or cell networks, attaching to more computers, servers, routers and modems and so on, and so on. There is no beginning. There is no end.


Map_of_the_Internet

In the image above, you are looking at one very small part of the Internet. See that star-burst like image it is extracted from? Go take a look at the full image. It takes awhile to load. Then come back, of course.

What makes the Internet work at all, is something called the Internet Protocol (IP). You may have heard of the term IP Address. Now you know what the IP stands for, but do you know what it is? A protocol is a set method for a way of doing things. Think of an incoming phone call. Typically it goes like this: you hear the phone ring, you pick up, you say “Hello…” and maybe a little more like, “…this is Guy speaking.” Then the person on the other end acknowledges you with something like, “Hey Guy, this is work. Where the heck are you?” Then the lying, I mean conversation, begins. That’s a socially accepted phone call protocol.

That’s basically how the Internet works. You tell your computer to connect to a resource, let’s say MakeUseOf.com. Just pulled that out of my hat. MakeUseOf.com is a human readable form for the IP address 216.92.56.91. Who’s going to remember that? Exactly.

So we have something called a Universal Resource Locator (URL) like MakeUseOf.com. Something called a Domain Name Server (DNS) which looks up that URL and then figures out the IP address associated with it. Think of a REALLY big phone book. You look up your plumber’s name and then you figure out what his phone number is. Same deal. Makes sense so far? Relax, there is no quiz and your Internet Users License won’t be revoked.

IPv4_space

What the above image shows is the available IP version 4 (IPv4) space. MakeUseOf.com is located in the 216 block. Remember that from the first 3 digits of the IP address? That block belongs to ARIN - American Registry for Internet Numbers. Kind of like how the area code 403 belongs to Alberta. Got’er figured?

Here’s where it gets a little crazy. Each piece of data you send out is broken down into packets. Imagine mailing your friend a book, page by page. Each page will have to carry your friend’s address and the page number to let him know what order it goes in. It should also let him know how many pages there are, so he knows when he has it all. They should also have your address, so if the mail person can’t deliver it, they know where it came from.

So, each packet carries the intended IP address, a number to determine where the packet fits back into the data sent, how many packets to expect, as well as your IP address. Crazy huh? It has more than that, but that’s the really important stuff. Check it out in the packet header below. I highlighted the stuff we talked about in green.


packet_header

Now, check this out. Each packet doesn’t necessarily go down the same set of wires to its destination. “What kind of glue are you on, Guy?” No, it’s true. Those packets go out to a device called a router, which then sends the packet to the nearest available router that is closer to that destination, and, hopefully, isn’t too congested. It figures that out based on the numbers in your IP address. The first three numbers identify a large area, and the rest make it more specific. Yet again, just like a phone number. This is known as ‘best-effort-delivery’.

So one packet may get routed through Virginia and another may go through Vancouver on their way to the same server in Hong Kong. This also means that packet A might get there later than packet B, or not at all! See what I mean about the miracle of a working Internet?

When the packets arrive at the destination, the server or computer receiving it compiles it into something cohesive, or it puts the book back together, to carry on that metaphor. Now the computer receiving all the packets sends back a message to the originating computer to say, in effect, “Thanks! Good-bye.” Thus the communication ends.

That’s the simplest, high-level overview I can give on how the Internet works. Take what I’ve said and add in millions of servers, routers, modems, and other networking devices and you can see how the complexity is magnified exponentially.

Next time you get an error message or a page loads a little slower than normal, reflect on this article and relive the amazement that the thing works at all. It’s all perspective, my friends. And lots of wires.

ഡബിള്‍സില്‍ നാദിയ ഡബിള്‍ റോളില്‍

ഒരുകാലത്ത്‌ കുടുംബ പ്രേക്ഷകരുടെ ഇഷ്ടതാരമായിരുന്ന നദിയാ മൊയ്‌തു മലയാളത്തിലേക്ക്‌ ശക്തമായ തിരിച്ചുവരവിനുള്ള ഒരുക്കത്തിലാണ്‌.മമ്മൂട്ടി നായകനാവുന്ന ഡബിള്‍സില്‍ നായികയാകാന്‍ താരം ഡേറ്റ്‌ നല്‍കിക്കഴിഞ്ഞു.

മോളിവുഡിലേക്കുള്ള തിരിച്ചുവരവ്‌ ഒരു വമ്പന്‍ ചിത്രത്തിലൂടെയാകണമെന്ന നദിയയുടെ തീരുമാനമാണ്‌ ഇതോടെ ലക്ഷ്യം കാണുന്നത്‌. ഡബിള്‍സില്‍ ഇരട്ട സഹോദരിമാരുടെ വേഷത്തിലാണ്‌ നദിയ അഭിനയിക്കുന്നത്‌.

Change Drive Letters in Windows XP

When you add drives to your computer, such as an extra hard drive, a CD drive, or a storage device that corresponds to a drive, Windows automatically assigns letters to the drives. However, this assignment might not suit your system; for example, you might have mapped a network drive to the same letter that Windows assigns to a new drive. When you want to change drive letters, follow these steps:

Right-click My Computer, and then click Manage.

Under Computer Management, click Disk Management. In the right pane, youll see
your drives listed. CD-ROM drives are listed at the bottom of the pane.

Right-click the drive or device you want to change, and then click Change Drive
Letter and Paths.


Click Change, click Assign the following drive letter, click the drive letter you want to assign, and then click OK.

Robot can perform surgery on beating heart

Waseda University's heart rate compensation system allows beating hearts to be operated on...
Coronary artery bypass surgery is used to treat angina and coronary artery disease, but the delicate nature of the operation means that it usually requires the heart to be artificially stopped. Scientists at Japan’s Waseda University have changed the game by creating a machine that can perform surgery on a functioning heart by adjusting to the rhythm of its beat.

Robotic surgery allows doctors to operate on patients by controlling a machine that is far more sterile, precise and flexible than the human hand. By calculating the movement of a heart with millimeter accuracy and shifting its instruments accordingly, Waseda University’s robot can operate on a beating heart as if it was frozen.

The Waseda crew’s robot has been operating on pig’s hearts since 2004, with a claimed 95% tracking accuracy. The goal now is to get it up to 98% before it can brought into an operating room.


Samsung watch phone calls in early

Looks like Samsung is going to beat LG to the punch with the release of its S9110 watch phone due to hit stores before the rival LG GD910 – in France anyway. Aimed at Dick Tracy fans and gadget lovers alike the S9110 even manages to squeeze a few more features into its diminutive body, including a larger 1.76-inch touchscreen (to the GD910’s 1.43-inch), Bluetooth 2.1 and Outlook email sync.

Like the LG GD910, the Samsung offering also packs an MP3 player, speakerphone, and voice recognition. The watch phone also supports 900/1800MHz, is powered by a 630mAh battery, and has 40MB of internal memory - so you probably won’t have enough room for your entire music library. The 176 x 220 pixel, 262k color TFT TSP display is protected behind scratch-proof glass and the stainless steel body measures just 57.5 x 41.1 x 11.98mm and weighs 91g.

The Samsung S9110 is set to hit shelves in France this month for around EUR€450 (approx. USD$639 at time of publication), a month ahead of the LG GD910. No word on wider availability as yet.

Who owns the Internet?

Imagine you're in a room full of people from different countries, and everyone only speaks his or her native language. In order to communicate, you'd have to come up with a standard set of rules and vocabulary. That's what makes the Internet so remarkable: It's a system that lets different computer networks communicate with each other using a standardized set of rules. Without rules, these computer networks wouldn't be able to communicate with each other.

Think for a minute about the scope of the Internet. It's a collection of inter-networked computer systems that spans the entire globe. It depends on several sets of rules called protocols. These protocols make it possible for computer communication across networks. It also relies on a huge infrastructure of routers, Network Access Points (NAPs) and computer systems. Then there are the satellites, miles of cable and hundreds of wireless routers that transmit signals between computers and networks.

It's a truly global system. Cables crisscross countries and oceans, crossing borders and linking some of the world's most remote locations to everyone else. And the Internet is still growing. More computers link to it every day, and various organizations and companies are working to extend Internet access to countries that aren't yet connected.

The Internet is a giant system made up of much smaller systems. If it's one thing, does it have a single owner? Is there some person or entity that controls the Internet? Is it possible for someone to own something that spans nations and oceans?

Creating a list of files within a directory

There’s been so many times where I needed to get a list of files that reside within a certain directory. There’s software out there to do it (like DDFilecatcher), but who wants to pay for it? It seems like it would be so simple just to create a little script that’ll take the names of all the files I have in a folder and save it to a .txt file. Well, here’s how you do it.

  1. Open notepad
  2. Put this code into the file

    dir /b>filelist.txt

  3. Save it as “filelist.bat”
  4. Place filelist.bat into the directory you need to get the list from
  5. Click on filelist.bat from within the folder
  6. You’ll now have a .txt doc called “filelist.txt”
  7. Simple, right? This has saved me so much time… it’s ridiculous.
